Sony has released the latest firmware update for PS4, bringing it up to system software version 6.20. This mandatory update doesn't seem to bring any new features to the console, instead simply keeping everything ship shape, as per usual. "This system software update improves system performance," our PS4 tells us.
Firmware update 6.20 isn't particularly big, weighing in at just 450MB, so it won't take you long to get it downloaded and installed. We did wonder if this update would be introducing PSN name changes to more people, seeing as the firmware version for the name changing beta is 6.10. However, we can't see any options to change our username after installing firmware 6.20. Still, it's a required update, so set it to download, but come back and leave us a comment while you wait.
